IMPROVEMENTlN APPARATUS FOR TRIMMING THE HEELS 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 13?,293, dated April 1,1873 application filed March 6, 1872.

To all whom it may concern:

Be it known that I, LOUIS Corn, of the City of St. Hyacinthe, in thedistrict of St. Hyacinthe, in the Province of Quebec, Canada, haveinvented new and useful Improvements on the Apparatus for Trimming theHeels of Boots and Shoes, and for retaining them in position during theoperation; and I do hereby declare that the following is a full,

clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing, where- Figure 1represents a side elevation of the trimming apparatus. Fig. 2 representsa front elevation of the trimming apparatus. Fig. 3 represents a partback elevation of the trimming apparatus. Fig. 4 represents a plan ofknife-carrier lever. Fig. 5 represents a modification of the jack usedin combination with the trimmer when stoga boots are operated upon. Fig.6 represents details of modification of knife-carrier. Fig. 7 representsa side elevation of the parts represented in Fig. 6; and Fig. 8represents the pivot-plate, by means of which the compressingarms areconnected to the tool.

This invention has reference to further improvements on the apparatusalready invented by me, and for which Letters Patent of the UnitedStates, No. 104,560, bearing date the 21st of June, 1870, and No.109,300, dated November 13, 1870, have already been granted I to me, thepurpose of these improvements being to adapt it for more general use,and give greater facility in operating it.

In the drawing, similar letters of reference indicate like parts.

Letter (1 is the lever, the eye 11 of which fits on the pin 1), made inthis case of such length as to allow the whole trimming apparatus, whennot in use, to be moved back, and hang down clear of the shoe-holdingmachine used in combination with it, thus saving time, and being farmore convenient for the workman, than having to pick up the apparatusand adjust it at each heel cut. The lever a and knife-carrier n are inall respects similar to those for which I have already obtained Let tersPatent, with the exception that at the point 1, in Fig. 1, a joint isformed, an elevation and plan of the exact construction of which areshown in Fig. 6, one end being pro vided with a double eye, a, and theother with a corresponding single eye, ubwith a pivot, u connecting themtogether. to are slots cut correspondingly through a and a, in which areplaced bolts '0. By this means the end of at, having the handle Iattached, can be set in various positions, to adapt it to moreconvenient use.

cured a metal guide, m to slide on the plate 4, acting as a guide forthe knife on the lower edge of the heel; and if desired for adjustment,the holes of the screws by which it is attached may be slottedvertically. The plate .9, having, as in the before-patented invention,the knuckle-joint .9 secured by the nut .9 and being itself attached tothe holding apparatus by the movable pivot 8 has its upper extrem' ityterminated in a long elbow, t, of the configuration shown, and havingpivoted to it the pin 15, acted upon in this case by a bow-spring, t*.This is for the purpose of giving the room required for the legs ofstoga boots, and to enable them to be held securely 'while beingoperated upon by the trimming apparatus.

Having thus described the construction and operation of my invention, Iclaim as follows: 1. The knife-carrier a, constructed with joint at 1,substantially as described.

2. The plate 8, in combination with the elbow t, pin 15, and spring 25,substantially as and for the purposes described.
